To all whom 'it may concern.'

Be it known that I, JOHN S. HADDEN, a subject oi the King of Great Britain, (who have declared my intention of becoming a citizen ofthe United States,) residing at Huntington Park, in the county of Los Angeles and State of California, have ipvented new and useful Improvements in Lawn-Sprinkling Devices, of which the fol lowing is a specification.

T his invention relates to lawn sprinkling devices, and more particularly to that special class of lawn sprinkling means or devices which is or are permanently installed in position :tor use and service, being suit ably connected with piping for supplying water.

In accordance with the present invention, l provide a sprinkling or spraying device for .lawns which comprises an immovable member set into the turf, land a movable member co-acting therewith and provided with a specially organized part or portion for effectual spraying or sprinkling, such latter part or portion being normally chambered within and protected by the immovable member. This movable member is projected into operative position above the turf by the force. oi' the head of water supplied to the device by a suitable service pipe, and when the head of water is cut oii the mov*- able member drops into housed position within the immovable member, within -which it is thoroughly protected against damage or deteriora-tion, and presents no obstruction to traverse of the lawn.

"he invention has' for its object to provide improvements in lawn sprinklers or sprayers oi. the general character stated which will 'be superior in point of relative simplicity and inexpensiveness of construetion, positiveness in operation, length ot lite and durability, freedom from liab'lity of damage or disruption and convenience in installation, and which will be 'generally superior in etliciency and serviceability.

The present invention is disclosed and was originally claimed in another applica! tion for Letters Patent filed by me June lf3, 1911, Serial No. 632,967; and the present invention relates particularly to the movable member of the lawn sprinklin device and the organization thereof for e ectnally spraying or sprinkling.

ivided and this application filed October 19,

With the above and other objects in view, the invention consists in the novel provision,` formation, construct-ion, combination, associati-on and relative arrangement of parts, 'members and features, all as hereinafter described, shown in. the drawing, and iinally pointed. out in claims.

ln the drawing, Figure l is a top plan view of a lawn sprinkling or spraying device constructed and organized in accordance with thel invention; Fig. 2 is a central vertical section ci the same, taken upon the line 2m?, Fig. l, and the device being shown as installed in a turfed lawn, the parts being in inoperative position; Fig. 3 is a view similar to Fig. 2, the parts being shown in operative position; Fig. {lis a detail transverse sectional view, taken upon the line en, Fig. 3, and looking in the direction ot theappended arrows; and Fig. 5 is a partial detail transverse sectional view 75 taken upon the line 5 5, Fig. 3, and look i ing in the direction Vof the appended arrows.

Corresponding parts in all the figures are designated by the same reference charaeters. so

Referring with particularity to the draw ing, A designates the immovable member and B designates the movable member et a sijirinkling device or sprinkling orV sprayingl means organized and constructed in accord 8L ance with the invention, theimmovable member being installed in the lawn formation in connection with a .suitable service pipe not shown, extending beneath the surface of the lawn, which is designated at G, c designating spears of grass which, as shown in Fig. Q, may overlie both members A and B when the movable member is in lowered or inoperative position; such blades of grass being thrust aside by the member B as it is projected upwardly into operative position as shown in Fig. lil. The member B is provided with a water directing portion whereby the water passed to the same, as hereinafter de scribed, is broken up en mosse and directed in lthe iorm of spray or finely divided particles over the adjacent lawn area. The member B is preferably rotatively mounted in connection with. the member A, and the water directing Aaortion 7) is formed to cause the' rotation of t e member B and thus eitect or enhance the performance of distributing,v the wateras last stated, The impact et the ,smaller external water upon the water directing portion t) causes the rotation of the member B.

The member A comprises a tubular body 6 which is connected with the service pipe as by a threaded coupling 7, and is provided at its upper end.I with a tubular casing 8the upper portion f which is open and installed so as to be iush` with the surface of the lawn formati on. l

The member B comprises a tubular stem 9 bepeath the lower end of which is secured'a wire loop 9B as a guard to prevent the stem 9 from displacement, the stem 9 being of diameter than' the internal diameter of the tubularfbody 6, and carrying at its upper end the water directing portion b which is mounted upon the stem 9 by abearing device D which enables the portion b to rotate upon the upper end of the ste-m 9. Normally, the stem 9v is chambered in the .body 6,. and the portion lb and the bearing device D are chambered in the casing 8, the bearing device Dlimitin'g the downward movement of the `=member B when the latter is in chambered position, by engagement 'of the bearing device D with the bottom bf the tubularl casing 8. The tubular casing 8 is of' enlarged diameter, with relation to the tubular body b', and the bottom portion oi the former, exteriorly of the body 6, is provided with a plurality of openings 10 which permit water or other substances collecting in the casing 8 to pass downwardly out of said casing and into the earth. l

The lower end of the casing 8 is provided with a downwardly extending tubular nipl ple 11 within which is threaded, at its upper portion, a tubular nipple 12 the lower portion of' said nipple 12 being spaced 'from the lower portion of the nipple 11l so as to permit the tubularbody 6 to be engaged-with the same threads, whereby the nipple 12 at its upper portion is threaded to thenipple 11. The lower portion of the tubular nipple 12 is formed into a conical valve seat 12FL ground to tit a corresponding conical valve or head 12" itted to the lower end of the tubular stem 9. The valve or head 12b is seated upon the valve seat 12EL when the stem 9 is in raised position. A slight play is allowed between the valve head 12b and the innervwall of the body 6, and between the stem 9 and the inner wall of the tubular nipple 12, to prevent clogging of the movement l of the member B, asby sand or other'foreign substances, which are permitted to escape through the small spaces provided between the stem 9 and the nipple 12 and between the head 12b and the bodyV 6. The lower end of the body 6 is disposed lin a plane slightly above 'the lower conical portion of the valve head 12", when the same is in extreme lowered position, and is countersunk or beveled slightly to conform to the conical formation of the valve head 12.

Leraars into the upper end ot the stem 9 is screwed above the upper end of the tube 9 and is surrounded by an annular bearing member 14, having a. base iiange 15 which rotates upon the upper end of the stem 9, the bear4- ing member 11 being held to the bearing member 18 by a lock-nut'lG threaded upon the upper end of the bearing member. 13.V The parts 13, 111 and 16 constitute the bearing device D and are preferably formed of suitable material to withstand corrosive and erosive action. j i

Threaded upon the annular bearing member 1l, ext-eriorly of thet same, is a base-ring 17 from which rise two diametrically opopposite vertical curvature and transverse 'outer edge curvature as shownin Fig. 5, said blades expanding laterally upwardly and merging into a conical fiat-topped crown 19. The parts 17, 18 and 19, together' with an adjustable water regulating and spreading device,Y constitute the water directing portion Z); said device consisting of a downwardly directed conical head 2O disposed centrally between the plates or blades 18 directly over the upper end of the tubular bearing member 13, and having a screwshanlr 21' threaded in a suitable chamber in the conical crown 19, so that the head 2O may be adjusted toward or away from the upper end of the bearing member 13 through which water issues after traversing the tubuconical head 20 is directed thereby to the curved plates or blades 18 which causes, by reaction, rotation of the water directing portion Z), and projection of the spray or finely divided water laterally from the porgtion Z) and over the lawn surface, the basering 17 and bearing member 1li rotating upon the bearing member .13. rlhe quality of the spray, and the nature of its deflection or direction mined by the position of adjustment of the. conical head 20. `When the head of water is turned oit, the vparts will be in the positions shown in Fig. 2, with the stem 9 chambered 9'and the tubular bearing member 13 so as i 125 to be directed against the plates or blades 18 and the conical crown 19, causing rotation of the waterl directing portion b, as above stated, and a broad scattering or spraying orn the linely divided water over the lawn sur- .,face. When the water is turned oit, the

' posed curved'delectors or blades 18, having lar stem 9. The water striking upon the by the portion b, will be `detera tubular bearing member 13 which projects l member B and its parts drop into housed positions, as above stated, and as shown in Fig. 2, Whereiirthey are effectually protected from damage or deterioriition, the uppermost portion of the same being flush with the surface of the lawn formation C. The several parts and members 'may be readily taken apart for cleansing or repair, or tor packing, and the thread formations are such that rotationV of the member B tends to cause a tightening of the several threaded connections.

I do not desire to be understood as limit ing myself to the specific provision, formation, construction, combination, association and relative arrangement of parts, membersl and features shown and described; but reserve the right to vary the same, in adapting` the improvements to varying conditions of use, Without departing from the spirit of the invention and the terms of the followingl claims.

Having thus described my invention, I claim and desire to secure by Letters Patent l. In a device of the character described, a member coniprising a tubular stem, and a Water directing portion rotatively mounted upon said stem in position to receive water traversing said stem; said Water directing portion being provided With an adjustable device disposed above said tubular stem.
